Hi there,
I just got an old Diamond without a battery and would like to see, if it still works. Connecting it with the power cable, nothing happens. But I guess, this is normal, at least my Touch HD can't be started without the battery inside.
However, is there a way to start the phone although it has no battery in it, but the power cable plugged in? Somehow bridging the gap or something? I have no idea.
I already ordered a battery, but it takes another two weeks until it arrives.
Thanks!
you could start it attached to dc power supply, like that (mine is the same)

Sorry, don't have such a machine. I only have this usb power supply.
no chance to do that then
btw, maybe you could help me in neighbour thread?
Ok so this nook was bought brand new in December 2010 For my mother In-law. She hasn't used it much. So I asked if I could put Android on it? She said sure cause she hasn't used it at all. As a matter of fact the NC was totally dead when she gave it to me. So I get back to my house and put it on the stock charger. I let it charge for 2 hours. I picked it up and turn it on and all I see is this message: Battery too low to power ON. I did a search and turned up similar problems but the nc where all rooted. I'm wondering if other people have had this same problem? And what they did to solve this as it is more then likely an easy fix. A. Take it back to the store and exchange it. Or. B. Send it off for repairs. C. Someone On XDA has the answer.
Also I've done some trouble shooting like trying to reset it. Also I've used 3 Other chargers and its still not charging or turning on.
Edit: It turns on it just stays at the screen with a red battery displaying the message in the title. Also after charging for a while the screen kind of lites up like its going to turn on but only goes black after that and then comes back to the same red battery screen.

what are you charging from? are you using the stock nook cable and plug?
Yes. And charging it from the wall outlet. Did that with the stock charger. my charger from my HD2 and also tried with the charger from my vibrant. All have the same affect. It has the red battery and the messege below and it also has been a total of 6 hours of charging 2 hours each with the all the chargers.
That stinks. You may have to contact B&N for it. If your using the stock and other chargers then it must be a battery failure.

Yeah seems to me thats what it must be I'll post back what I find out.
When that message is displayed, try holding the power button for 30+ seconds and then turning it back on.
That has worked for me the couple of times it seemed stuck on that screen.

If you're using other chargers, it's possible that you've damages the usb port. The NC uses a non standard usb port, which has two stages. The first stage is standard 5 pin uusb communication, the second stage is non-standard 12 pin charging...

Non-Standard chargers...
As far as I can tell it works fine with any microusb cord.
Their charger cables break...(bend and break) very easy. I have gone through 2.
The upside is that their charger provides power far faster than the normal microusb cords.
At this point...I'm charging mine almost exclusively from my stock evo cord.
If you don't turn off the screen when charging...it may not have enough power coming in to actually build a charge without their cable.

I never used another charger besides the stock charger that came with the NC. Up until this happened all that was ever used was the stock cable for charging. I only used another charging cable once I ran into these problems cause I figured the cable was damaged. Its happened to me before with other devices. But the same results happen with every cord I use. When I plug it in it lights up and shows the red battery screen. So that tells me that the cord or USB port couldn't be the problem. Cause its clearly getting power its just not charging.

No. They sell it without one...the 8GB internal storage is enough for looooottts of books. The microsd was just a nice + for people with lots and lots of music.
I had this issue as well, but I found a fix!
No matter what I did or how long I let it charge, it would always have that red low battery icon.
What I ended up doing to fix it was opening up the back of the unit and disconnecting the battery cable from the unit. I then plugged it directly into the wall without the battery connected to see if it would boot, though I don't know if that was necessary, I don't even remember if it booted that way or not.. I think it did not.
Anyway I unplugged the power cable again, reconnected the battery, then plugged in the power cable and tried to boot and it booted up perfectly after that. The battery icon indicated 13% charge, but it quickly charged back up just fine.
FYI I left the unit in the car overnight right before this happened, and it was pretty chilly that night, 10-20 degreed Fahrenheit. I suspect that caused the issue for some reason, so I've been sure not to do so since.
P.S. I had to do a fair amount of googling around before I found good instructions on taking apart the NC. I think I had to take off the 2 screws under the SD card slot and use a butter knife to just pry the back off. It's just held in with clips and you can't tell it was opened except for the little stickers over the screw holes.

Thanks for the feed back. I'm wondering by un-pluging the battery from the nook if it resets it. Kind of like if a phone freezes or if your computer freezes and you pull the battery. Seems like a plan. Not sure if this is what I'll do as I'm sure its still under warranty. If it comes back and its not covered or B & N wont replace it I guess thats my only hope.
im having the same problem as well it was off for a while and now its at the red batter screen. i guess ill try and take it apart?

If your not worried about voiding the warranty then sure I guess its worth a shot.
So I got it fixed right. All it was was a faulty cable lol!

I had this problem too, but I'm not sure "faulty" is the right word for the cable.
My friend borrowed my nook and returned it with a dead battery (Thanks asshole). So I plugged it into my computer at work and just got the always-on low battery message. After 45 minutes I took it to my car so I wouldn't forget it. I plugged it into my USB charger in the car using a different cable. Two hours later, same state.
When I got home I pugged it into the Nook wall charger with yet another cable (not the nook's original) and got the same thing. I searched here to see if I could figure out what was going on and decided to try the original cable with the wall plug. literally two seconds after plugging it in it started booting into Froyo.
I'm sure I didn't have four "faulty" cables. I think those that are saying you should be using the original are correct. The others worked fine when the battery wasn't empty, but mine only responded to the original once it got to the point of the unending low-battery message.
Original charger / cable required with totally empty battery
Same here. With battery completely empty and non standard cable,stuck at red battery sign forever. With orginal cable, boots fine and charges.
solution I found
Have CM7 installed on SDCard, got the battery icon, even with the unit plugged into the charger with oem equipment. Held the power button 'til the unit turned off completely, removed the sdcard, rebooted. Nook booted into stock fine, turned off, re-inserted sdcard and rebooted. All is well.
Okay, first thing to mention is that I have searched for information on my issue and while I have found (and tried) solutions that approach my goof, I need to post this:
Last night I finished reading from Kindle app, hit the power button to shut off the screen and laid it down. I know I should have plugged it to recharge but too late now. I am running CM nightly from 07172012, so I know I didn't download the nightly CM battery issue versions.
This morning the screen will not light up; I have tried charging it, hard reset with power and home screen buttons for 15-20 seconds (and longer), and nothing works. My concern is that the screen is dead. I connected the touchpad to my laptop and I get the connection sound from the laptop; it sees the TP but does not accept it as a portable storage device. Device Manager lists it as: QHSUSB_DLOAD with driver(s) not loaded.
When I try the volume rocker button I do not hear the small audible ping as volume goes up or down. Of course, with the resets, who knows where I am in the OS (or even if it is WebOS or Android).
I really didn't want to be a noob and post this, but I need some advice from the brethren here on XDA. Thanks in advance.
It seems to me that it's not even booting if your getting that strange device in device manager. Try the webos recovery tool from hp. It may help. Although it will wipe android off.

my son-in-law is in the same boat. Nothing he does wakes it up. I believe there are tp's out there with this hardware issue. I let my tp battery drain completely. It powers down around 4% battery. I place it on the touchstone, it charges backup and boots into moboot, then webos. I've done this twice. no problems. If it's under warranty still, send it in.
If you have a touchstone charger put it on that and leave it for a couple of hours and it Will come back to life.
See this article by Reverend Kyle http://www.reverendkyle.com/index.php/articles/146-hp-touchpad-charging-issues-solution
I hope this helps.
I've had multiple instances of black screen of death failure.
The latest one I had, I was able to restore by using a standard USB to micro USB cable (and recently NOT the HP OEM cable) to connect to the computer I usually use to sync or use HP web doctor with.
Same symtpom as the OP, get the three dings when connecting the touchpad to the computer, no responses and the QHUSB driver load error. HP charger wouldn't chage it, touchstone would not charge it.
Anyhow, I left it connected for a few hours to charge connected to my PC. Then, I disconnected from the PC using the large USB connector and reconnected. Whamo, got to the bootloader.
I believe what happened was I trickle charged the touchpad enough to get the touchpad to boot.
You can try the various hard boot keypresses too, but wait for a few hours while trying to trickle charge the touchpad via the computer USB.
Update
Okay, so I followed the old rule of doing the simple (and/or free) solutions first and then move on.
1) I set the touchpad on the touchstone for several hours yesterday - no luck
2) I connected the touchpad to my pc through the USB and let it charge - no luck
3) I let it be plugged into the standard charging plug all night - no luck
4) I prayed to the great old god Cthulhu - no luck
My only option remaining is to use WebOS Doctor. One question on that: in all the literature I have read thus far (and perhaps I am mistaken), I need to be able to get the TP into USB mode to download the corrections/reboot back into WebOS. Is that right or can I expect that when the doctor sees the mangled mess of an OS through the USB connection, it will know what to do?
Again, as always that for the previous posts and for the support.

Another piece of black magic that worked for me and is worth a try as it is free. Connect Touchpad to standard HP brick charger plugged into power outlet. Unplug cable from charger, count to 5, plug it back in, count to 5, take it back out. Repeat the cycle until you get bored or until you get a red charging symbol. If you get the latter then let it charge up normally and you are back in business. The theory behind this method is that it takes a few seconds on plugging in for the circuits to realise they "shouldn't be charging" and this allows a little bit of charging to take place on each insertion. Repeat enough times and you get enough to kick start the proper charging. In my case about 20 times did the trick.
As I didn't want to get into this situation again I then set up a Tasker process to power down th eTouchpad if the battey charge dropped below 8% and I've been OK since.
RIP Touchpad / EOT
Well, I had to wait a day to get my hands on a WinXP laptop; I upgraded my Dell to Win8 about 3 months ago and WebOS Doctor does not play well with Win8.
While that time passed, the touchpad finally gave up the ghost. There is no power left in the TP. When I run WebOS Doc the laptop cannot see the TP connecting via USB. I also checked by connecting the TB to the Dell, since it would at least see the device. Not any more.
My thanks again to those that responded. I did try the plug in, plug out with 5 second waits between, just in case. You never know. However, after 50+ attempts I had to call it a no-go.
does your home button light come on at all? Are you able to see moboot bootloader at all or are you able to start the tablet in webos recovery mode by holding the vol key while powering it on? are you able to ./adb connect? Also I've never had much luck with the resest method youre using, holding down the power and home key, I always hold down the power key and press the home key 15 times, when I get hard freezes and lockups, it's always worked.
Mine is in the same boat for a couple of months, removed battery and charged. Boot loader is borked I get only get a qualcomm usb device but nothing thats of any use for webos doctor or qualcomm tools. We'll have to wait until someone figures out jtag or how to replace the bootloader with qualcomm tools. I'm amazed with the number of touchpads out there that something hasn't leaked from hp to fix it. Anyone got friend in hp or qualcomm :angel:
OP Update
Well, I thought this was a dead issue but here is the latest.
After wallowing it a pit of despair the likes of which can only be described as wretched, (I even coveted my wife's TP up close, almost giving into temptation and swapping decals to reverse ownership) I looked outside of XDA and did general Google searches and happened upon this site:
http://forums.webosnation.com/hp-touchpad/299256-dead-touchpad.html
After reading a bit I realized that the touchstone may be able to recharge the dead battery even though fully drained. I began the quest that Friday morning the 24th of August, after verifying that my Dell laptop did not see the TP when plugged in via the USB cable.
I just did a quick check and the laptop now "sees" the TP when connected. Still no luck on booting into Moboot or the USB icon screen - neither Power and Volume Up or Power and Home buttons achieve anything. But I am glad to see that the touchstone has placed enough charge into the battery that the laptop is aware of the TP when connected.
I believe that given a few more days on the touchstone I should be able to boot into moboot.
@ haxin - I have nothing. Not a single light from the Home button - my only evidence that there is SOMETHING going on is when I connect the TP to the laptop and get my connection "sound". Again, I have high hopes that the touchstone will get me where I am going, albeit at a snails pace.
@ paddy - Yeah, I hope that when (if) I get to a lit screen, I am able to move past where you are at. My big concern is that I am toast even with a semi charged or fully charged battery from the touchstone.
I will update later on. Again, thanks to all for the input and probing questions. You have made me think harder and work a bit longer on this project.
OP Update - 31 August
After 7 days on the touchstone, the touchpad is currently showing the low battery charge icon; I have now plugged it into the A/C adapter.
Each morning I have picked up the TP, held down the power button and held the home button for 15+ seconds. Today it worked, turning on the screen for the first time in a week and letting me see the low battery image.
In my quest to resolve this issue, I have read so many variations on what buttons to hold and how long to hold them that after awhile you end up considering the possibility that SOME of the button options are not correct. That the operator has booted their TP up, but they misconstrued the actual solution; how else can you explain the idea that HP built so many different button combinations and hold times to boot a TP from a nearly or fully dead battery state?
Anyway, I will continue to post updates until my beloved TP is back to running CM9.
And to all those who gave their TP up because the battery got too low; find a touchstone or other "trickle" charger solution, connect and let it sit for a week or so.
Thanks!
Glad the Touchstone worked for you , don't know why it has taken so long to charge but when your up an running properly Llama is a good app to install as
A:You can set alarms for when the battery gets to a certain level/levels
B:Have it shut down when the battery gets to a certain level.
I use 20% for an alarm and 10% to shut down which allows me to sleep easy and not worry if someone else is using it . .
I am up and running. I most definitely will load that app on my TP, plus my wife's and a coworker who bought a TP because of mine.
I don't know either why it took so long; I am just glad it worked and I have it back. I am on it right now.
Thanks again to all who provided feedback and guidance. This is why I love XDA.

HP Touchpad sleeping and will not turn on
Just a note to those HP tablet owners who experience the Black screen of death or sleep of death.
I am the proud owner of 4 HP tablets and two of them so far have had the black screen of death. I have read forum after forum trying to get answers to this problem. There was only one posting that has made cense to me. Someone posted that the tablets symptoms are very much like when the Phones use to go to sleep. The solution was to disconnect the battery for a few minutes then plug it back in. Then simply hit the hold the power button down to turn on the tablet.
The problem is taking the TP apart. There is a video on youtube on how to disassemble the tp. It is a little annoying that you have to go to such lengths to reset the hardware but HP will charge you 250 dollars to fix the problem. After you watch the video on how to open the TP, remove the 3 little screws holding the battery. Now slowly pry the battery up, they use double sided tape to hold it in place along with the screws. Wiggle the battery side to side and try to disconnect the battery connector. This can be done without removing the boards in the TP. Wait 1 min then try to replace the connector in the socket. It is on the underside of a board so when you have it in place use something to make sure it is tight. Plug the charger in to the USB cable. Without closing up the unit hold the tablet power button in until you get the battery charging symbol on the display. Let the unit charge while it is still disassembled. Just in case you have a problem. Once everything is operating disconnect to charger and replace the battery screws, now snap everything together.
This was the only way I was able to fix two of my four TP's. I am sure I will have to do this again because my kids always let the tablets go dead and they don't pay attention when placing them on the Stone for charging. If the tablet is not properly placed on the stone the tablet will not charge.
Hope this helps.
This by far is the best tablet for the money anywhere.

I realise this is an old thread, but I recently had a reoccurrence of the black screen of death issue and thought given the number of touchpads still out in the wild, I would share my experience on the off-chance it may help somebody.
My first experience of the black screen issue was a few months after having my touchpad (many years ago). The screen just went black and no combination of holding the reset keys for any period of time would restart the unit. I had suffered lock-ups before and found the reset combination to be successful, but this time none of that worked and I had effectively what appeared to be a dead unit.
Having contacted HP, I returned the unit under warranty and a unit was returned working. I say “a unit” as I was never quite sure if it was the same unit or a refurbed unit, but to be honest given the speed the units went out of stock during the fire sale, I was just glad to have a working unit again.
Well this week after several years of use including the installation of Android, the black screen occurred again. As before, no combination of the keys / holding for a period of time / pressing them a number of times etc had any effect. The unit was three quarters charged and I was using it up till the point the screen went black. :crying:
Given that the unit has no warranty and it was “dead” anyway, I decided to take it apart. Despite watching YouTube videos, this appeared to be more troublesome than I thought, but eventually I was in. Interestingly, the backlight on the screen was still lit, suggesting the unit was still powered. I did consider disconnecting the battery, having removed the screws as per the previous poster, but mine seemed to be well and truly stuck down and I felt I may damage it prying it away from the base.
However, looking around inside the unit, I spotted what was clearly a surface mounted switch that faced upwards towards the back of the screen. Out of interest, I pressed on this switch with my finger nail and my unit powered off (shown by the backlight turning off). I then pressed the normal power switch and the unit powered up as normal. I have attached a photo of the switch which resides close to the popout tab with serial numbers on that can be found on the right hand side of the unit.
It does appear strange that HP put this “reset” button inside the unit, facing inwards rather than outwards where a small hole in the back of the case could be used to press it. So if you do get to the opening the case stage, consider this as an alternative to prying the battery loose. Also if somebody can work out a way to make the button accessible from outside the case it might be a useful modification.

Oh I was so keen when I came across this post. A Reset Button! How great would that be?
Tried it, unfortunately it did not resurrect my dead as a doorstop TP. I was so hoping...
I just put a 'new' EBay battery in it a couple of days ago and tried trickle charging with a 1000mA charger for 24hrs. No joy there either.
All I get when I plug it into the PC is that it shows up as a "QDLoader 9008" (QHSUB_DLOAD driver) .
No flicker of life or light whats so ever...

Try to borrow a Touchstone conductive charger if you can. It's the only thing that has worked for me when it has totally drained down.
All the best.

That's what I was thinking - no joy there either... It is not even showing signs of getting the least bit warm.
I keep thinking and hoping that there is some way to resurrect this one but I may be wrong...
It's currently trickling on a 1000mA charger. Tomorrow I'm going to try the Touchstone behind it.
If that doesn't start something then I'm going to yank the new battery and along with the old battery charge them like an RC device.
(if I can ascertain the proper way to do that --- )

After several days on the trickle, still no life.
Took it apart at lunch and with the battery still connected to mobo it is showing 3.1V across the red/black. So I figure the battery
is good. Looks like the mobo is gone.
Not sure what else to try.

Hello everyone,
I installed a JB rom a few weeks ago on my TP (can't remember which one)...it worked for a little while, then i wanted to flash something additional and it seems to be bricked ever since and has been laying around...which is why I can't remember what exactly I wanted to flash
Anywho, if i connect it to the PC the notification LED on the home button is blinking..but that's it. no combination of power/voldownup/home button seems to be working and when I try to run webos doctor it doesn't recognise my device.
can anyone please help me?
When you say bricked. Do you mean stuck in a boot loop wouldn't turn on etc.
Have you had it connected to the stock charger or better still on a touchstone and if so for how long.
The more information you can give the better.
No it doesn't turn on at all, screen stays black.
It's been connected to what i think is the stock cable to my pc (there are too many Micro-USB cables laying around here ) for about an hour now and i just put it on the touchstone (LEDs are still flashing)..
Leave on the Touchstone for at least a few hours preferably overnight then hold the power and volume up buttons for at least 30 seconds if nothing happens do the same with power and home buttons and post any progress or lack of, but the first thing is to try and put some charge into it and the best for that imo is the Touchstone.

The stock cable for the touchpad has a silver dot at each end. I have two touchpads ad the connection is very loose and unreliable. It often won't charge. I bought new Micro USB charge/sync cables and charging is no longer an issue.
The USB port on your computer is not powerful enough for anything it trickle charge. You need a stock touchpad charger.
Well i charged on the touchstone and then after a few hours i was able to boot into recovery and flash a new rom problem solved, thanks anyway!
I know that it has been said that "if your touchpad completely dies, you must have the OEM charger to start it back up". At first this seems true. . .However! I would like to report that twice now, when it was completely dead and displaying the "plug in the original charger for reliable charging or die because im a juice nazi", I was able after about 4 hours of just leaving it alone plugged into a 1amp phone charger, to get it to charge up and boot. This may have already been discovered but I couldn't find mention of it. Just wanted to give hope to someone that might have given up on this.

So when you connect 1 amp phone charger, does the TP says to connect the original charger? Even if it says to connect the original charger, and leaving it for 4 hours the TP charged is that right???
My problem is when I connect to cell phone charger, it says to connect original charger.
When I connect original charger, the TP stays at 0% even after connecting the charger overnight. I dont know what is the problem? is it charger, is it battery or is it TP..

The message will be displayed but it is gradually charging in the background. When it gets enough juice, it will start up and charge faster. In your case it sounds like either your port or battery are damaged somehow. Possibly the charging circuitry but that is unlikely. If you don't have an original charger or touchstone, then your options are limited. They aren't very expensive on ebay though. I would let it charge on a good 1 amp charger for a few days and see what happens then. Mine did the "soft brick" crap once where it was completely unresponsive and ran completely dead and i just charged it for 4 days and forgot about it and when i remembered it, it had powered on and booted. TPs are funny devices. Expect anything and report it if you don't mind. Maybe we can get this sorted out.

Thanks for prompt response..
I have original wall charger, and got a new cable from ebay. So I am hoping its equivalent to original charger. How can I debug if the port or battery is damaged.. any idea?
I left it on charge overnight yesterday. It was at 0, in the morning.. I left it on charge today before coming to office. i am expecting it to be at 0, when I go home.. When its connected to charger, its working normally (with 0 battery), but as soon as i remove from charger, it will shutdown..
Morning, when I was charging,
the battery monitor widget app showing Battery flow as "-600mA". I think this should be +ve while charging. the same app was showing status as "Charging AC plugged". I will try to charge my phone with the same cable and charger, if the phone shows +ve current flow, then, its deffinetly should be problem with the battery or touchpad right..
I wil test it in the evening.. and if its problem with battery or touchpad.. i will try to clean the TP and will try again.. Lets see how it goes
Ok so you have the original charger, great! And it boots into android/webos correct? It sounds like your A6 firmware might have crapped out or whatever it does to cause battery issues. Probably not bad battery if this happened rather suddenly, and its not a bad port if its booting and running while plugged, even if its not charging. . .so go here:
http://forum.xda-developers.com/showthread.php?t=2756314
and read it carefully! With this tool, you can do some really cool stuff including re-flashing the A6 battery monitor/control chip. It can (but might not) fix issues like this. Give it a try with a good cable and let me know what happens. Good luck!

I rebooted to webOS, and TP charged normally.. now i updated to CM11, all good as of now.. Thanks for helping me..
only bad part is i disassembled, before booting to webOS
Aw dude....well hey it happens to the best of us lol. Now u know a lot more about ur tablet and i would still recommend reflashing the A6 and removing webos if u dont use it. Tptoolbox can also be "installed" by renaming the boot image .bin file to uImage.TPtoolbox and placing it in /boot on your android partition. This allows moboot to see it. Off topic i know but i thought you might be interested. Best of luck with the re-assembly!

You can only install TPToolbox as described if you have removed WebOS.

why is that?

Because there's not enough room for both, and it's designed to run in the WebOS userspace. Don't even try it; I speak from experience.

Because the boot folder is not big enough with the webOS uImage.
Fixed my Touchpad!
I had the same issue and just wanted to report what worked for me. My touchpad wasn't responding to any button pressing combos and even after sitting on the charger for two days, didn't want to turn on. After some google searching I found my Touchpad might be so dead that the charging circuity might not want to charge the battery and all the fixes were telling me to take apart the Touchpad and charge the battery directly. That's not something I really wanted to do. Then another person suggested to charge the Touchpad with a lower amp charger, so I plugged the Touchpad into an iPhone charger for about an hour. I came back, held the power button and home button - nothing. Tried power, volume up, and home - nothing. But then I held the power button and hit the home button ~10 times and then... the home button started blinking left and right. YES! I took the Touchpad and put it on the original charger, 15 minutes later it had the Low Battery Screen and another 15 minutes later, Cyanogenmod was booting.
I need help. When I try to transfer the Android files to the HP TouchPad using TPtoolbox, Windows says that there is an F drive that I have to format before I use it. In the tutorials, a drive labeled HP TOUCHPAD or something like that shows in Windows, and you can put the Android files inside of the ttinstall folder. Should I format the drive and if so, what format?
Oh sorry, I posted to the wrong thread.
